Abstract :

N anotechnology has found application in many diverse sectors. Zinc oxide (ZnO) nanoparticles are one of the major engineered metal oxide nanoparticles in different consumer products. The present communication, using differential expression analysis of P53, Rasand cell signalling pathway proteins provides evidence for the genotoxic and carcinogenic effects of ZnO ENP in lymphocytes from healthy individuals as well as in patients suffering from lung cancer, chronic obstructive pulmonary disease (COPD) and asthma. In the present study, it was observed that lymphocytes of lung cancer patients were more susceptible to effects from ZnO ENPs exposure than the COPD and asthma patients. In general asthma patients? responses were very much similar to those from controls.
